Beyond weight loss: Impact of a weight management programme for mid-older Australians in private health insurance.

Weight-loss maintenance and lifestyle behaviour necessary to manage weight are undisputedly challenging. We evaluated a secondary prevention weight-loss maintenance programme for participants (n = 490) with weight-related chronic disease in the Australian private health insurance setting. This study investigated the impact of the maintenance programme on anthropometric and lifestyle risk behaviour changes after 6 and 12 months, and trends in weight-loss maintenance after 1 year. Using a pre- and post-test design, data were analysed with generalized linear mixed models for repeated measures to determine the effect of the programme on weight loss and lifestyle behaviour outcomes. After initially losing a clinically significant amount of weight (mean 9.1 kg), maintenance-programme participants maintained clinically significant weight loss (mean 7.6 kg) at 12 months. Rates of discontinuation in the programme were high (47% at 6 months and 73% at 12 months). Weight-loss maintenance was achieved by 76% of participants at 3 months and 62% at 6 months, stabilizing at 55% and 56% at 9 and 12 months, respectively. Greater initial weight loss was associated with weight-loss maintenance at 12 months. Participants <55 years demonstrated consistent weight-loss maintenance over this time but the odds for successful weight-loss maintenance for those ≥55 years continued to decrease over time. At maintenance-baseline, 68.3% of participants had sufficient physical activity for health; 61.4% and 19.8% met recommended fruit and vegetable consumption, respectively. All lifestyle risk behaviours were maintained at 12 months. A programme extending support strategies for maintaining weight-related behaviour shows promise to successfully support these changes over 12 months. There is a potentially important opportunity for targeted intervention at 6 to 9 months.

Sociodemographic and health risk profile associated with participation in a private health insurance weight loss maintenance and chronic disease management program.

Objective Identifying who participates in chronic disease management programs yields insights into program reach and appeal. This study investigated sustained participation in a remotely delivered weight loss maintenance program offered to Australian private health insurance members. Methods All participants completing an initial 18-week weight loss program were eligible for a maintenance phase. A pre-post test design was used and sociodemographic and anthropometric characteristics of those who did and did not opt in to the maintenance phase were compared using binary logistic regression. Results Maintenance phase participants lost more weight during the initial weight loss program (-2.2kg (P<0.001); body mass index -0.8kg/m2 (P<0.001)) than those who did not opt in. Participants who were obese (v. overweight) upon completion of the initial weight loss program were less likely to opt in to the maintenance phase (adjusted odds ratio (aOR) 1.76, 95% confidence interval (CI) 1.35-2.30, P<0.001) and participants aged ≥55 years were more likely to opt in (aOR 0.59, 95% CI 0.44-0.80, P<0.001) than those aged <55 years. Conclusions Understanding why health insurance members opt in to maintenance programs can assist the development of strategies to improve program reach. Younger participants and those who remain obese following a weight loss program may be targeted by private health insurers and service providers to increase weight loss maintenance program participation. What is known about the topic? Australian private health insurers offer chronic disease management programs to support members to manage obesity-related chronic disease. An 18-week weight loss and lifestyle modification program was extended to assist participants maintain weight loss and health benefits resulting from the initial program. This weight loss maintenance phase is novel in the private health insurance setting and is thought to be important to sustained health improvement. Although program reach is important to benefit those most in need, little is known about who sustains the use (or does not) of such programs. What does this paper add? This study provides an insight to the characteristics of participants more likely to opt in to a weight loss maintenance program. It highlights the sociodemographic and anthropometric characteristics associated with maintenance program uptake, identifying the subgroups less likely to opt in. These study findings are novel because they report on participation in a chronic disease management program with a focus on maintenance of weight loss. What are the implications for practitioners? These results will benefit private health insurers and service providers implementing maintenance programs for weight loss, providing an awareness of which participant groups to target to increase maintenance and reach. In addition, they offer avenues for future exploration, such as the generalisability and sustainability of chronic disease management programs. Although those not opting in are a difficult-to-access group, a qualitative study of reasons for not opting in to such a program would provide further information for program design, recruitment and retention.

"I'm Still on Track": A Qualitative Exploration of Participant Experiences of a Weight Loss Maintenance Program.

Qualitative evidence of participants' experiences of real-life weight loss maintenance programs is important for ongoing participant engagement and can inform program improvements. The purpose of this study was to understand how participants account for their engagement with a weight loss maintenance program and the role of the program in their weight management. A qualitative study using semi-structured interviews with 17 participants of a weight loss maintenance program was conducted; common themes were identified using a thematic inductive approach. Many participant narratives incorporated recurrent descriptions of their program experiences as a weight management journey. Our analysis generated four themes: returning to real life as a threat, the personal responsibility imperative, the program supporting agency and the program supporting self-regulation. The program, which provides external support and strategies, overlapped with the context of returning to real life and the personal responsibility imperative. Participant accounts of their journey at this intersection include the program supporting both agency and self-regulation which influences ongoing weight management. The interplay between themes identified and the maintenance program services allows compatibility between participants' sense of personal responsibility and the program components to help participants to 'stay on track' or 'get back on track'. In providing sufficient structure, opportunities to revisit successful strategies, and accountability, participants are empowered to overcome real-life threats and make positive health choices.

Healthy Weight for Life programme: Evaluating the practice and effectiveness of a weight loss maintenance programme in the private health insurance setting.

BACKGROUND: Australian private health insurers are increasingly involved in the delivery of chronic disease management programmes to their members, recognising the importance of decreasing and managing lifestyle risk factors and the impact such factors have on health service utilisation. One such secondary prevention programme is the Healthy Weight for Life programme, an intensive weight loss and lifestyle modification programme that has been designed for overweight and obese private health insurance members in Australia. Together with the insurer, the Healthy Weight for Life service provider developed and implemented a long-term maintenance programme that supports participants who complete the Healthy Weight for Life programme to maintain the weight loss they achieved during the programme. Various studies have shown that evidence-based weight management programmes can be effective; however, the results may vary in different contexts. OBJECTIVE: This article presents the evaluation rationale and framework designed to assess the process and impact of the long-term maintenance programme on weight loss maintenance, other health-related benefits and participants' experience with the programme. METHODS: The evaluation will comprise a number of inter-related sub-studies balancing evaluation of programme effectiveness and implementation. The maintenance programme presented a unique opportunity for researchers to partner with private health insurance and a service provider to assess a real-world programme in the under-researched area of weight loss maintenance in this setting and emphasises the importance of evaluating such programmes given the potential the private health insurance context has in the future delivery of health care.

Acceptability of financial incentives for maintenance of weight loss in mid-older adults: a mixed methods study.

BACKGROUND: Health insurers worldwide implement financial incentive schemes to encourage health-related behaviours, including to facilitate weight loss. The maintenance of weight loss is a public health challenge, and as non-communicable diseases become more prevalent with increasing age, mid-older adults could benefit from programs which motivate weight loss maintenance. However, little is understood about their perceptions of using financial incentives to maintain weight loss. METHODS: We used mixed methods to explore the attitudes and views of participants who had completed an Australian weight loss and lifestyle modification program offered to overweight and obese health insurance members with weight-related chronic diseases, about the acceptability and usefulness of different types of financial incentives to support weight loss maintenance. An online survey was completed by 130 respondents (mean age = 64 years); and a further 28 participants (mean age = 65 years) attended six focus groups. RESULTS: Both independent samples of participants supported a formalised maintenance program. Online survey respondents reported that non-cash (85.2%) and cash (77%) incentives would be potentially motivating; but only 40.5% reported that deposit contracts would motivate weight loss maintenance. Results of in-depth discussions found overall low support for any type of financial incentive, but particularly deposit contracts and lotteries. Some participants expressed that improved health was of more value than a monetary incentive and that they felt personally responsible for their own health, which was at odds with the idea of financial incentives. Others suggested ongoing program and peer support as potentially useful for weight loss maintenance. CONCLUSIONS: If financial incentives are considered for mid-older Australian adults in the health insurance setting, program planners will need to balance the discordance between participant beliefs about the individual responsibility for health and their desire for external supports to motivate and sustain weight loss maintenance.

Is There a Dose-Response Relationship Between Weight Loss and Symptom Improvement in Persons With Knee Osteoarthritis?

OBJECTIVE: We examined the dose-response relationship between weight reduction and pain/functional improvement in persons with symptomatic knee osteoarthritis (KOA) participating in a community-based weight loss program. METHODS: Consecutive participants with KOA and enrolled in the 18-week Osteoarthritis Healthy Weight for Life weight-loss program were selected. In this completer-type analysis, participants were assessed at baseline, 6 weeks, and 18 weeks for body weight and Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales. The dose-response relationship between weight-change categories (>10%, 7.6-10%, 5.1-7.5%, 2.6-5.0%, and <2.5% of body weight loss) and change in KOOS scores was assessed by repeated-measures analysis of variance, controlling for sex and age, body mass index (BMI), and KOOS. The Western Ontario McMaster Universities Osteoarthritis Index function score derived from the KOOS was used to assess a meaningful clinical functional improvement. RESULTS: A total of 1,383 persons (71% females) were enrolled. Mean ± SD age, height, and weight were 64 ± 8.7 years, 1.66 ± 0.09 meters, and 95.1 ± 17.2 kg, respectively. Mean ± SD BMI was 34.4 ± 5.2 kg/m(2) with 82% of participants obese at baseline. A total of 1,304 persons (94%) achieved a >2.5% reduction in body weight. There was a significant dose-response relationship between all KOOS subscales and percentage of weight change across all weight-change categories. Participants required ≥7.7% (95% confidence interval 5.2, 13.3) body weight loss to achieve a minimal clinically important improvement in function. CONCLUSION: There is a significant dose-response relationship between percentage of weight loss and symptomatic improvement. This study confirms the feasibility of weight loss as a therapeutic intervention in KOA in a community-based setting.
